Expert Answer
Number of oxygen atoms in 22 g of CO2 .
 
Molar mass of CO2 =12 plus 2 cross times 16 equals 44 space g
44 space straight g space of space CO subscript 2 space space represent space equals space 1 space mol
22 space straight g space of space CO subscript 2 space represent space equals space 1 space mol

22 space straight g space of space CO subscript 2 space represents space equals space 1 space mol cross times 22 over 44 equals space 0.5 space mol

Now comma space 1 space mole space of space CO subscript 2 space contain space oxygen space atoms equals space 2 cross times straight N subscript straight o equals 2 cross times 6.022 cross times 10 to the power of 23

0.5 space mole space of space space CO subscript 2 space contain space oxygen space atoms equals 2 cross times 6.022 cross times 10 to the power of 23 cross times 0.5 equals 6.022 cross times 10 to the power of 23

6.022 cross times 10 to the power of 23 space molecules space of space CO thin space have space mass equals space Molar space mass equals space 12 plus 16 equals 28 space straight g
